The following recommendations may be given with respect to the design of the recording chain:
- Choose a recording equipment that ensures a flat amplitude-frequency response within the required frequency range.
- Try to avoid components that may introduce linear distortions
in the form of spectral peaks, especially at medium and high frequencies.
- Avoid any overload or aliasing of a recorded signal since this
introduces critical non-linear distortions.
This has to be emphasised for digital recordings due to the sharp
clipping of all information above the most significant bit.
